A

In order to provide means for manually operating the pressure rolls a shaft 16 is mounted in suitable bearings 17 carried by a plate 18, fixed to the frame 1, said shaft being provided with a wheel 19 at it"-outer end by which the shaft can be manually rotated. The shaft 16 is also provided with a worm 20 meshing with a worm-gear L l fixed on the shaft 15 in order to oscillate the disk 14 and it will be seen that when rotated to the right, the operating rod 12 shaft 23 and the sprocket wheel 26 being fixed on the shaft 27, which is driven by the driving mechanism of the mangle not shown. Loosely mounted upon the shaft 23 are spaced beveled pinions 28 and 29 which mesh with a bevel gear 30 fixed on the inner end of the shaft 16 said pinions being pro vided with clutch portions 31 and 32 adapted to co-act with the double clutch member 34 feathered upon the shaft 23 whereby either one of said pinions can be locked to the driving shaft in order to rotate the bevel gear 30 in either direction in order to raise or lower the pressure rolls.

For shifting the clutch member 34 so as to lock e ther 'of the bevel pinions of the power shaft 23 we provide the frame with a pivoted clutch-throwing yoke 35, which is provided with a slotted extension 36 through which extends a bolt 37, carried by the lower end of a lever 38 pivotally mounted upon the bracket 22 as shown at 39, said layer extending upwardly and hav ing itsfree'end connected to a crank-arm 40 carried bv a shaft all mounted in suitable bearings' 42of a bracket 43 fixed to the frame 1 ln'a plane above the shaft 16, as

1 clearly shown. For operating the shaft 41,

we provide the outer end of the same with a lever 44 whereby the shaft can be rocked in its bearings in order to shift the clutch member. To provide tension means for win terin the clutch member when in neutral position, we provide the shaft ll with an arm 45 having a segment ll) at its and pro vidcd with a projection, the edges of which co-act with lhc free ends of a bowed-spring: i

47, as clearly shown in Fig. 5. and in dotted lines in Fig. 5. While we have shown this construction it is of course undcrst soijl,that

it is not essential, as the mechanism herein" after fully described for returning 'fthev clutch member to neutral position, is-sufiicient.

Supp-oriml by the shafts 16 and 41 is a. casing 48 inclosing' sprocket wheels 49 and 50 carried by the shafts 16 and 41, the sprocket 49 being loosely mounted on the shaft ll and the sprocket 50 fixed on the shaft 16 and passing over -e sprockets is a sproclmt-chain 5.1. as chwirly shown in Figs. 2 and (3, whereby the sprocket 49 will be rotated when the shaft it: is operated either by power or by hand. The sprocket 49 is provir ed with a projection 52 which is adapted to engage a springqn'essed pin 53 mounted in avv sleeve portion 54 of an arm 55 fixed on the shaft 41, said pin being provided with a knob fill at its outer end by means of which the same can be drawn out :of the path of travel oi? the progection 52,

of the sprocket 49 in order to allow the sprocket to continue its rotation so as to prevent the operation of the automatic means for returning the clutch member into neutral position. This provides means for throwing the pressure rolls into such position that the gears for driving the rolls will be thrown out of engagement with the cylinder gear whereby the rolls can be repaired or rerown'cil. "lhe sleeve portion 54-. of the arm 55 trawls in a. curved slot 64-, formed in the casin;- 8, c early shown in Fig. 2.-

In connectunz with the above mentioned mechanism, we provide 1: pressure indicaton.

which is connected to one of the pressure roll supports and as herein shown, comprises an arm 57 carrying an operating rod 58 which is adjustably mounted therein, as shown at 59,. the upper end of the rod being; connected to the crank arm of a pointer shaft 60. The pointer shaft is provided with asuitable pointer l l traveling over a dial (52, supported y a bracket ('13. secured to the frame.

The operation of the mechanism for raising' and lowering the pressure rolls is as follows: Supposing that the mechanism is in the position as shown in the drawing, by throwing the lever 44 to the left or over the designation Un marked on the casing 48, the clutch member 34- will be locked to the bevel pinion 31 causing the same to rotate therewith, which in turn will rotate the bevel gear 30 in the direction shown by the 1 arrow; so as to cause the worm meshing with the gear 2] to rotate the shaft 15, carrying with it, the disk .14 which will draw down on the opt. ling rod and ause the segm nt i! in late up n its pivot so as to br 'e; lilo o iv ne sl-s into such a position drawn down tionsr sprocket will be equal to the distance of travel of the operating rod in order to oh- I tain the desired pressure, whereby the projection '52, carried-thereby will be brought a into engagement with the pin 53 of the arm 55 so as to rock :the shaft 41 and return the lever 44 into a central or neutral position, which-in turn through the link connections will throw the clutch member 34 into neutral position so as to release the driving mech anism and the operating mechanism will, be

, brought to a standstill. It will be seenthat by this construction, the driving mechanism will be thrown out of operation at the desired time and' zthat by changing the sprockets for sprockets of different sizes, the shifting of the clutch can be regulated. The operation of lowering the rolls is the. reverse of.th'e raising, and as the sprocket 49 is loose uponjthe shaft 41, the same runs free until the projection carried thereby isbrought into engagement with the pin of the --'arm fixed on the shaft,'which will throw the "clutch member; into neutral position. Y By drawing outwardly upon the knob 56 and operating the hand-wheel 19, the pressure rolls can be raised and lowered manually and when it is desired to mechanically control the same, it is only necessary to release 1 the knob and oscillate the lever 44 into either the off or on posit-ion, as the case may be, which in turn will throw the clutch into cngagement'with one of the bevel pinions so as to cause the worm-shaft to rotate in the desired direction so as to raise or lower the pressure rolls.

From the above description it will be seen that we have provided automatic means for controlling the raising and lowering of the pressure rolls, the connection between the worm-shaft and lever shaft forming means -for, automatically throwing the driving said mcchanisnn'a power control for said X'driven shaft, a lever actuated shaft, a conneetion between said lever shaft and, power control, means revolving loosely upon said lever sliaft actuated by the raising mecha Qnisin and coactii g =peritulically with said i shaft f forautomatically returning said ""power control to neutral position.v
